An outage of Amazon’s Elastic Compute Cloud in North Virginia has taken down Netflix, Pinterest, Instagram, and other services. According to numerous Twitter updates and our own checks, all three services are unavailable as of Friday evening at 9:10 p.m. PT.

Amazon’s service health dashboard indicates that there are power issues in its North Virginia data center, most likely caused by severe storms in the region. The outage underscores the vulnerabilities of depending on the public cloud versus using your own data centers.

I bet most people don’t realize that these services are all connected. I’m surprised that Amazon doesn’t have redundant data farms.
